IMPROVEMENT IN TOBACCO-CURING APPARATUS.

Specilcation forming part of Letters Patent No. 125,277, dated April 2,1872.

' Specification describing a Process and Apparatus for YellowingTobacco, and subse- 4quently rendering it pliable, invented by 'tionofthe adjustable evaporator, provided with subjacent chamber forcoal-box.

A is a tobacco-house;4 B B, furnaces opening on the outside, andprovided with shields B, on the inside of the building. C are section alheating-pipes. D are vaporizers, placed in adjustable frames D', andupon said pipes. E are charcoal boxes; and F the chimney of the furnace.a are set-screws; b, dampers; and c. connecting and detachable ilangeson the end of pipes C'.

YVater is placed inthe evaporators D which rest near the heating-pipesC. Tobacco is hung up in the house A, th`e"latter is tightly closed, andthe fires started in the furnaces. As the pipes radiate heat into thechamber, the vaporizers D inoisten the air, thus producing a high butmoist temperature, which superinduces the yellow color desired. When thetobacco has been yellowcd to the satisfaction of the operator, the wateris drawn from the val porizers; a gradual increase of heat is thensecured for drying the lea-ves, stalk, and stem.

The tobacco is now cured. The furnace fires are now put out and thevaporizers raised and filled with water. The boxes E, provided withcharcoal lires, are then placed beneath the vaporizing-kettles andcaused to evolve aqueous Vvapor into the air until the 'tobacco is sufnciently impregnated therewith, made pliable, and can be handled withoutfracture. The heating-pipessare made in readily detachable sections, andconnected by flanges c, so that they may be conveniently taken apart andcleaned.

Having thus described all that is necessary 'to a full understanding ofmy invention, what I esteem to be new, and desire to secure by LettersPatent, is-

1. The process of yellowing tobacco by api plying heat and steamsimultaneously and previous to the process of drying the leaves andstems, as described.

2. I claim, in tobacco-houses, the :arrangement of the furnaces B on theoutside and with shields B on the inside, in order to distribute theheat more equably through the building, as described.

3. The vaporizers D, arranged on adjustable frames D, which themselvesrest on the heating-pipes C when yellowing the tobacco,

'butare raised to receive thereunder the charcoal boxes E, whenmoistening it, all as set forth.
